Researchers at the Wyss Institute have developed a technique for 3D printing metallic structures without requiring auxiliary support material. A special ink composed of silver nanoparticles is deposited through a nozzle and annealed using a precisely targeted laser to solidify the ink. The nozzle can move along the xyz-plane while a rotating stage allows for curved structures.
The technique is promising for the creation of highly customized curved electronics and flexible biomedical devices.
